Country list with flags

[guicuton]

It's possible use this directive with images on span options like a list of country with their flags?
Checking the original DOC we should use

function formatState (state) {
  if (!state.id) {
    return state.text;
  }
  var baseUrl = "/user/pages/images/flags";
  var $state = $(
    '<span><img src="' + baseUrl + '/' + state.element.value.toLowerCase() + '.png" class="img-flag" /> ' + state.text + '</span>'
  );
  return $state;
};

$(".js-example-templating").select2({
  templateResult: formatState
});

How do i could implement the templating options with mdr?
